Centrifugal filtration units, Vivaspin® 2

Vivaspin® concentrators are disposable ultrafiltration devices for the concentration of biological samples of 0,4 to 2 ml.

High retentate recovery >90%
Vertical membrane design for ultra-fast concentration
Safe sample concentration due to dead-stop volume
Convenient concentrate recovery by pipetting
Volume graduation for easy reading/monitoring

Vivaspin® 2 can effectively be used in swing bucket or fixed angle rotors accepting 15 ml centrifuge tubes. The patented vertical membrane design and thin channel filtration chamber (US 5,647,990) minimises membrane fouling and provides high speed concentrations, even with particle-laden solutions. Vivaspin® 2 combines the speed of the classic Vivaspin® products with low internal surface and membrane area in order to achieve superior recoveries from very dilute solutions.
